strace

I'm quite new to strace / netstat / etc. I'm using this command to get a trace of the apache process handling my request (telnet), is there a way to simplify it a bit?

sudo strace -o /tmp/strace -f -s4096 -r -p $(netstat -antlp | \ 
    grep $(lsof -p `pidof telnet` | grep TCP | \
    perl -n -e'/localhost:(\d+)/ && print $1') | grep apache2 | \ 
    perl -n -e'/ESTABLISHED (\d+)/ && print $1')

Thanks!
